What does 1 Samuel 16:17 mean?
God has rejected Saul as king (1 Samuel 13:11–14; 15:17–29) and removed His Spirit from Saul. Now, "a harmful spirit from the Lord" torments Saul (1 Samuel 16:14). This seems to be a demon whom God permits to afflict Saul for his disobedience. Saul's servants and advisors may not be aware that Saul has been rejected as king, but they are aware of the affliction. They have suggested a remedy: bring in a lyre-player. The effect of music on emotions is known and employed to this day.Now Saul agrees to their plan and tells them to find him a man who can play the lyre well and bring him. The lyre was a stringed instrument somewhat like a small harp.
